This week, many of us are starting our well-intentioned New Year's resolutions—or at least trying to. And if your goal this year is in the realm of losing weight, eating healthier, or simply trying to cut out empty, excess calories, listen up: the World Cancer Fund released a report showing that people who drink get 10 percent of their daily calories from alcohol. (Eek!)

So, if you pour yourself a big 'ol glass of wine the moment you get home from the office (which we've been known to do every now and then), it can set you back 178 calories—which would take at least a half hour of serious power walking to burn off.

Not that we're saying you need to immediately hit the gym to counteract each drop of booze you imbibe (actually, doing so could be rather dangerous), but there is a big drawback to getting your calories from vino, beer, or mixed drinks. Unlike real food, or even other beverages like fruit juice, alcohol is made up of empty calories. There's no energy-boosting protein, nutrient-rich antioxidants or vitamins—just sugar. So, it's definitely a good idea to know how much you're drinking—calorie-wise—if you have health- or weight-related goals you'd like to hit.

To that end, the World Cancer Fund has this handy-dandy calculator that tells you how many calories are in certain drinks and how much exercise you would need to do to counteract them. (Which, not gonna lie, is really fun to play around with.) Just be sure to wait until you're sober to jump on the elliptical, okay?
